A sheet formed from a carbon fiber reinforced thermoplastic resin with a simplified production process and excellent mechanical characteristics, and a production method of said sheet is provided. This sheet is formed from a carbon fiber reinforced thermoplastic resin that contains carbon fibers, dichloromethane, and a thermoplastic resin containing at least one of a polycarbonate resin and a polyarylate resin, and the content of the dichloromethane contained in the sheet is 10-10,000 ppm by mass.

Sheet formed from carbon fiber reinforced thermoplastic resin, and production method of said sheet

A sheet formed from carbon fiber reinforced thermoplastic resin with high heat resistance, and a production method of said sheet is provided. This sheet is formed from a carbon fiber reinforced thermoplastic resin that contains carbon fibers, dichloromethane, and a thermoplastic resin containing at least one of a polycarbonate resin and a polyarylate resin. The aforementioned at least one of a polycarbonate resin and a polyarylate resin has a constituent unit derived from a dihydric phenol represented by formula (1), and the content of the dichloromethane contained in the sheet is 10-10,000 ppm by mass. (In formula (1), R-Rindependently represent a hydrogen, a halogen, a nitro, or a methyl group; X represents a divalent group represented by any of formulas (2) to (4).) 

A sheet formed from carbon fiber reinforced thermoplastic resin with high moldability, and a production method of said resin is provided. This sheet is formed from a carbon fiber reinforced thermoplastic resin that contains carbon fibers, dichloromethane, and a thermoplastic resin containing at least one of a polycarbonate resin and a polyarylate resin. The aforementioned at least one of a polycarbonate resin and a polyarylate resin has a terminal structure derived from a monohydric phenol represented by formula (1) and a constituent unit derived from a dihydric phenol, and the content of the dichloromethane contained in the sheet is 10-10,000 ppm by mass. (In formula (1), Rrepresents an alkyl group with 8-36 carbons, or an alkenyl group with 8-36 carbons, and R-Rindependently represent a hydrogen, a halogen, an alkyl group with 1-20 carbons optionally having a substituent, or an aryl group with 6-12 carbons optionally having a substituent.) 

The present invention can provide a polyarylate obtained from a dihydric phenol component and an aromatic dicarboxylic acid component. The polyarylate is characterized in that the dihydric phenol component contains a compound represented by general formula (A) or (B) as a primary raw material, and the pencil hardness of the polyarylate is H or higher.  

Polyarylate and molded article using same

The present invention can provide a polyarylate obtained from a dihydric phenol component and an aromatic dicarboxylic acid component. The polyarylate is characterized in that the dihydric phenol component contains a compound represented by general formula (A) or (B) as a primary raw material, and the pencil hardness of the polyarylate is H or higher.  (In the formula, Rand Reach independently denote a hydrogen atom, an alkyl group having 1-6 carbon atoms or a phenyl group. However, neither Rnor Rrepresents a methyl group.)  (In the formula, Rand Reach independently denote a hydrogen atom or a methyl group. In addition, a is an integer between 4 and 11. However, a is not 5 if Rand Rare both hydrogen atoms.)

A synthetic resin laminated sheet, in which whitening, cracking, and foaming do not occur when thermoforming is carried out, in particular when deep-draw molding is carried out, and defects do not occur during lamination of a hard coating layer; and a molded article obtained by molding the laminated sheet. A synthetic resin laminated sheet has a coating layer, which includes an acrylic resin, laminated on one surface of a substrate layer including a polycarbonate resin in which a monohydric phenol represented by general formula (1) is used as a chain terminator and is obtained by reacting the monohydric phenol with a dihydric phenol and a carbonate binding agent and has a viscosity average molecular weight of 18000-35000. (In the formula, R1 represents a C8-36 alkyl group or a C8-36 alkenyl group. R2-R5 each represent hydrogen, halogen, or an optionally substituted C1-20 alkyl group or C6-12 aryl group).
